class—not about math, but about life—would be things she would remember long after the math skills had faded away．As I finished reading, I remembered why I had become a teacher．

Regular child care provided outside home or by someone other than the mother does not in itself undermine （削弱） healthy emotional connections between mothers and their 15-month-old infants（幼儿）, according to a long-term national study．The finding holds even if care begins during the first 3 months after birth and runs for 30 hours or more per week．
Among infants who receive unkind and unresponsive care from their mothers, however, the mother-care relationship may be damaged．\care that have not previously been studied in detail,\contends （主张） Jay Belsky, a psychologist at Pennsylvania State University．Belsky and several of his colleagues announced their findings last week at the international conference．
The investigation consists of 1,153 children and their families living in or near Boston．The youngsters, no more than 1 month old when entered the study in 1991, will be tracked until the age of 7．Experimenters gave questionnaires to mothers in their homes and videotaped baby caretaker?s interacting with the kids at ages 1, 6, and 15 months．Independent observers rated the quality of each child care efforts and noted infant nervousness．Unlike most previous studies, this one allows researchers to observe each caretaker?s personality at child nursing, and kid?s emotional reaction by the equipment．After taking family factors into consideration, other psychologists state that the researchers found no relation between the quality of child care and infant?s response．But the experimenters contend that the boys who spent more than 30 hours per week in child care exhibited more emotion for their mothers than other boys who didn?t, and the girls who spent the same hours per week in child care showed a modest （适度的） rise in this emotion．Therefore, quality of child care outside home plays an important role in the connection between mothers and infants．

A．mother care is the best according to a national study

Like many other nations, China has been busy putting together evacuation （撤侨）plans for its citizens stuck in crisis-torn Libya．The real surprise has been just how many Chinese are living there．The foreign ministry does not know for sure but puts the figure at 30-40,000．
The huge contingent （代表团） in Libya, who work for at least 27 Chinese companies, has brought to light one of the new dilemmas facing China as its economic interests expand．For a mixture of reasons that are partly political, partly business, Chinese workers are now present in many of the most unrest and dangerous parts of the world, including places where anti-Chinese sentiment over jobs and working conditions is on the rise．One of the first wake-up calls was in 2007, when a group of Chinese women were kidnapped in Pakistan, an event which led to the siege of the Red Mosque in Lahore．In the same year, nine Chinese oil workers were killed in Ethiopia．In recent years, Chinese workers have been kidnapped in Cameroon, Congo and Afghanistan．
Publicly, Chinese diplomats admit that the country needs better contingency plans to deal with this sort of situation．Privately, they worry about a different issue: that such incidents will force them to get much more involved in domestic political disputes in far-off lands, pulling the government away from its commitment to a policy of non-interference．The nightmare, a few diplomats and academics admit, would be a large, violent attack on a group of Chinese which then prompted an intense nationalist reaction at home, forcing the government to take the sort of interventionist （干涉主义的） actions it tries to shun． Beijing gave some indication of how it will respond in the future with the decision on Thursday to send the frigate（护卫舰） Xuzhou, currently conducting anti-piracy tasks off the coast of Somalia, to Libya．Its mission will be to help the evacuation effort, but it is also a warning to any in Libya who might attack Chinese interests, as well as the latest indication of the growing global reach of China?s navy．As Andrew Erickson, a China expert at the US Naval War College says: “This latest initiative（方案） is part of a larger ongoing increase in Chinese power, presence, and influence around the world, and should come as no surprise．China has global interests, cannot free ride forever, and requires a presence in critical areas and situations in order to have a voice．”

Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri（MU） researchers are developing a nuclear energy source that is smaller, lighter and more efficient．
“To provide enough power, we need certain methods with high energy density（密度）”，said Jae Kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope（放射性同位素） battery can provide power density that is much higher than chemical batteries．”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems （M/NEMS）．Although nuclear batteries can cause concerns, Kwon said they are safe．
“People hear the word ?nuclear? and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems．”
His new idea is not only in the battery?s size, but also in its semiconductor（半导体）．Kwon?s battery uses a liquid semiconductor rather than a solid semiconductor．
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure（晶体结构） of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem．”
Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery?s power, shrink its size and try with various other materials．Kwon said that battery could be thinner than the thickness of human hair．
